Seven functional traits of the absorptive roots of 240 individuals of 52 species, soil properties and air temperature were measured along an elevational gradient on Mt. Fanjingshan, Tongren City, Guizhou, and then the direct and indirect effects of these controls on species distribution were detected.Results: Absorptive roots adapted to air temperature with two strategies. The first strategy was positively associated with the specific root area(SRA) and specific root length(SRL) and was negatively associated with the root tissue density(RTD), representing the classic root economics spectrum(RES). The second strategy was represented by the trade-off between root diameter, mycorrhizal fungi colonization(MF) and SRL, representing the collaboration gradient with “do it yourself” resource uptake ranging from “outsourcing” to mycorrhizal resource uptake. Air temperature regulated species distribution in six ways: directly reducing species importance value;indirectly increasing the species importance value by reducing soil nitrogen content or increasing soil pH by reducing soil moisture inducing absorptive roots to change from “do it yourself” resource absorption to “outsourcing” resource absorption;indirectly decreasing the species importance value by decreasing soil moisture to change from“outsourcing”resource absorption to “do it yourself” resource absorption;indirectly increasing the species importance value with increasing soil pH by reducing soil moisture resulting in absorptive root traits turning into nutrient foraging traits;and indirectly decreasing the species importance value by promoting absorptive root traits to nutrient conservation traits.Conclusions: Absorptive root traits play a crucial role in the regulation of species distribution through multiapproaches of air temperature.展开更多

文摘Background:To analyze the expression of cluster of differentiation 80(CD80)/cluster of differentiation 163(CD163)in colorectal cancer(CRC)patients and their correlation with the syndrome of traditional Chinese medicine,pathology and prognosis.Methods:(1)The correlation between the pathological characteristics of 232 postoperative CRC patients and the deficiency and excess syndromes of traditional Chinese medicine was analyzed using the chi-square test,Spearman’s correlation,and Cox regression methods.(2)Immunohistochemistry and quantitative real-time PCR were used to detect the expression of CD80 and CD163 in cancer and paracancer tissues of CRC patients.(3)The relationships between the changes of CD80 and CD163 and the prognosis of CRC patients with deficiency syndrome.Patient survival were analyzed using cardinality and Cox regression proportional-hazards model regression.Results:(1)The degree of differentiation and tumor node metastasis stage of CRC were statistically different between patients with deficiency and excess syndromes(P<0.05);carcinoembryonic antigen and carbohydrate antigen 19-9 were highly expressed in the excess syndrome group,and both were significantly correlated with the distribution of traditional Chinese medicine syndromes(P<0.001);deficiency and excess syndromes,and carbohydrate antigen 19-9 were all independent factors affecting the postoperative survival of CRC patients.(2)The distribution of post-operative survival in CRC patients was significantly correlated with the distribution of the disease type(P<0.001).(3)The expression levels of CD163 protein and message RNA were significantly higher in CRC cancer tissues than in paraneoplastic tissues(P<0.001);whereas the expression of CD80 was significantly higher in paraneoplastic tissues than in cancer tissues(P<0.001).(4)The expression levels of CD80/CD163 were significantly different in different parts of the tissues of patients with deficiency and excess syndromes(P<0.001).(5)CRC patients with high CD80 expression and low CD163 expression had longer survival cycles(P<0.001).Conclusion:The malignant progression of CRC patients with deficiency syndrome is faster than that with excess syndrome.The correlation between deficiency and excess syndromes and the expression levels of CD80 and CD163 could be an independent risk factor for the survival prognosis of patients with CRC.
文摘BACKGROUND Malignant peripheral nerve sheath tumor(MPNST)is a rare and aggressive soft tissue sarcoma that poses a major diagnostic and therapeutic challenge.CASE SUMMARY We retrospectively reviewed patients with head and neck MPNSTs treated in our hospital from 2000 to 2021.The clinical features,pathological manifestations,treatments,and prognoses were summarized.We also reviewed the literature,focusing on MPNST in the mandible and maxilla.The study population consisted of five women and five men aged 22–75 years(mean age,49 years).Of the 10 patients,7 were initial cases and 3 were recurrent cases.All lesions were sporadic.The most common site was the mandible.The most frequently encountered symptoms were a progressive mass and local swelling.Complete or partial loss of trimethylation at lysine 27 of histone H3(H3K27me3)was evident on staining in four of nine cases(one case was excluded due to lack of tissue for evaluation of loss of H3K27me3).The 2-and 5-year disease-specific survival rates were 86%a nd 43%,respectively.The average survival time was 64 mo.CONCLUSION MPNST is a highly malignant tumor with a poor prognosis,prone to a high risk of recurrence and distant metastasis.Complete surgical resection is the main treatment.
